Drawing pad



Patented May 2, 1933 WALTER D'REIFUSS, OF NILES CENTER, ILLINOISDRAWING- PAD Application filed June 24,

The present invention has for its object the provision of a drawing pad,includingamong other features a base or backing characterized by twostraightedges along one side and end thereof, said straightedgesprojecting slightly above the uppermost page of the pad and beingsuitably graduated so that a triangle or other suitable draftinginstrument can be readily and conveniently used in conjunction therewithfor drawing vertical and horizontal lines Without the use of a T-'square.

One of the chief characteristics of the invention resides in gluing allof the pages of the pad together along their corresponding outerlongitudinal edges, the other free longitudinal and corresponding endedges lying against the straightedges of the backing, whereby theuppermost page of the pad is always held in a proper position for use.

The nature and advantages of the invention will be better understoodwhen the following detaildescription is read in connection with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views and wherein:

Figure 1 is a plan view of the pad showing a drawing instrument reposingthereon.

Figure 2 is a sectional view on line 22 35 of Figure 1.

- Figure 3 is a sectional view on line 33 of Figure 1.

The drawing pad forming the subject matter of the present inventioncomprises a base or backing 10 which may be constructed from anysuitable material and also vary in size without departing from theinventive idea. This backing is characterized by two straightedges 11and 12 respectively, the lat- 45 ter being secured upon and arrangedalong 1930. Serial No. 463,434.

one longitudinal side and jen'dedge of the backing as illustrated.These'straightedges and the backing may be made of cloth board oranyother suitable material andmay' be 4 discarded after the pages 13 havebeen used. The straightedges are preferably graduated as illustrated tofacilitate the use of a draft ing instrument 14, herein illustrated asan L-square.-

In accordance with the'present invention the pages 13 which repose uponthe base or backing 10 have their corresponding outer longitudinal edgesglued together, and also to the adjacent edge of the base 10, whiletheir opposite free longitudinal edges, and the corresponding free endedges lie within the angle formed by the straight edges and preferablyin contacting engagement With the adjacent straightedg'es ll and12'respec- I tively. 'The remaining free end edgeslfi terminate flushwith the adjacent edge of the base or backing 10. By reason of thisconstruction each uppermost page is effectively held in position foruse, as the'outer'longitudinal edges are secured together, whilelfl thecorresponding side and end edges are nested against the straightedges.Each page can of course be easily and conveniently torn from the pad, byseparating it from the outer longitudinal glued edge 15, and-as abovestated When the pages have all been used, the backing in its entiretymay be discarded, being very simple in construction and cheap tomanufacture.

By reason of the pad having its glued edges 90 lying elsewhereflthan atthe corner acent the vertex of the angle formed by straight edges, thesheets may be torn from the pad without the danger of leaving at thecornerv residual glue or glue and adherent torn parts I of the paper.Such residue Will prevent the proper use of a triangle or other likeinstrument when it is desirable to lay an edge thereof on thestraightedges'near the corner. By

reason of the glue being entirely on an outer 99 edge, or on all theouter edges there is no danger for such residue being left at any partof the straightedges.

While it is believed that from the foregoing description, the nature andadvantages of the invention will be readily apparent, I desire to haveit understood, that I do not limit myself'to what is herein shown anddescribed and that such changes may be resorted to when desired as fallwithin the scope of what is claimed.

What I claim as new is:

1. A drawing padcomprising in combination a backing, a pad oi sheetmaterial secured to the backing, and straightedges along two adjacentand perpendicular sides of the backing projecting above the level of thepad, the sheets of said pad at the edges thereof adjacent thestraightedges being mutually separated and free.

, 2. A drawing pad comprising in combinationa backing, a padof sheetmaterial secured to the backing, and straightedges along two adjacentand perpendicular sides of the 2 backing projecting above, the levelofthe pad, the backing on the sides opposite said straightedges beingunobstructed at the drawing level of the pad, and said pad being locatedwithin the angle of said straightedges Q; in close proximity thereto,and having the sheets at the corner in theangle mutually separate andfree. I e

3. A drawing pad comprising numerous sheets of material for the receiptof drawing and like marks, a backing for said sheet straightedgesarranged along one side and end of the backing to include said sheets inthe angle between them, said sheets being united in a unitary pad andvhaving their Q edges adjacent the straightedges mutually separable andfree.

4. A drawing outfit including a backing, straightedges secured along oneside and one end of the backing, a plurality of'sheets united into a padand secured to said backing in the angle formed by said straightedges,the

edges of the sheets of said pad being in substantial contact with saidstraightedges, said sheet edges being mutually free and sep- 9; arable,and other edges of the sheets and a coincident edge of the backing beingglued together. i j

' 5. A drawing outfit including a backing, straightedges secured alongone side and one 53 end of the backing, a plurality of sheets unitedinto a pad and secured to the backing, said pad lying below the level ofthe straight.- edges and in the angle formed by said straightedges, theedges of said sheets being 2in substantial contact'with saidstraightedges, and being mutually separable andfree. In testimonywhereof I aflix my signature.

WALTER DREIFUss.
